Ok since people may be hearing a lot of rage about CoD MW2 with the no dedicated servers and 60 dollar price point here is a look at the information that was given out buy a dev and the podcast where it was said
http://bash.podbean.com/2009/10/17/bash-123-pwnt/

summary

* We're doing a lot on the backend to make the game accessible for everyone.
* There is no delay for the PC version of MW2
* There's prestige mode
* Jason West at the MP event, said that he was dead on, on the matchmaking servers. We've been building a system on the backend called IW.NET.
* You are completely reliant on IW.NET. There are no server lists. There are no dedicated servers.
* You have private matches where you can customize the game
* You cannot put MW2 on a dedicated server.
* This is the first time we've ever done something like this and the team has huge plans for what IW.NET develops into.
* Customizing your game...you have quite a few options in a private match
* You're getting same game (as in Console), plus matchmaking and private match.
* Server admin point-of view, NO DEDICATED SERVERS

* IW partnering through Steam is what you will see in the future. Matchmaking is not through Steam, but IW.NET is run in conjunction with Steam.
* GSP's will no longer be renting out servers.
* No PunkBuster. VAC will be used as an anti cheat.
* Retail distribution: Pre-orders will get a disk. Or you could order from Steam.
* DLC may now need to be paid for
* Piracy was only a small reason for going to IW.NET - not the whole reason.

Clans:

* No more clan servers. Private matches, replace clan servers.
* Listen servers will connect to each other.
* IW.NET/Steam will replace the community server admin

Competitive Gaming

* Competitive gaming has changed as we know it.
* It might be possible in the future for IW engineers to load a "competitive" setting on IW.NET, but it is far from a guarantee. It might also never happen.

Modding

* Modding the game is now very much in question. Fourzerotwo had no info on modding. However, it appears that there will be no community mods or maps for MW2.
* Modding in SpecOps? Unknown.

I recently broke news on a PC community member’s podcast that Modern Warfare 2 would be introducing a completely new backend infastructure called IWNET that would allow matchmaking for multiplayer games on PC. The news, by default, means no more browsing through a Server List for a server with the settings / ping you want among other things, and sent shockwaves through the hardcore PC community, leading to many more questions than answers as to ‘HOW’ this would work, and if it would really be better for the PC community as a whole.Questions, assumptions, and speculation I intend to dispel.Call of Duty: Modern Warfare 2 is actually the biggest investment Infinity Ward has ever made into the PC version of our games. It’s also the most feature-rich PC version we’ve ever made. IWNET takes the benefits of dedicated servers and allows them to be utilized and accessed by every player, out of the box, while removing the barrier to entry for players unaware of how to maintain a server on their own.How does it do this?Matchmaking & Smoother Gameplay: When you want to player a multiplayer game on PC, in the past. You’d have to scroll through a Server Browser which listed every available server which was hosted by individual server admins. Each had their own private rules, mods, or ways of playing the game. Most players would also use the server browser to find just the best quality game (based on PING). With IWNET matchmaking, it takes all that into account for you. All you have to do is select the playlist (pre-set gametypes with custom rules) that fits the style of play you are in the mood for. When you do, it will automatically find you a game with the best performance, ping, and preferences based on your location and individual connection as well as matching you with players of your same SKILL. So you’re always guaranteed the best game performance for where you are and what connection you’re playing on as well as an equal game with other players of your same skill level, not rank, but skill level. It doesn’t mean you’ll just be thrown into a random game! It will put you in the game that will give you the smoothest gameplay possible without you having to manually find a server with the best ping.Playlists and Private Matches: As I described above, Playlists are pre-set game modes and gametypes for public games. If you just want to jump into a public game of Search and Destroy or Hardcore Search and Destroy and you don’t care about fully customizing it, then you can utilize playlists to do that quickly for you. However, say you’re in a clan and you want to play a Clan match with another team, or you want to practice for an upcoming tournament that has specific rules in a private game. Then you can start a Private Match (which is essentially like running your own private server) where you have complete control over the rules, who can join, boot players you don’t want, and essentially control the entire game or tweak it to your liking. Once the rules are set, you can invite the other team in or just start it up with your clan to practice with the custom rules before the match. This now allows you to play custom games out of the box without the need to install mods, find a modded server with the rules you like, or worry about not being in control of the match.Party System and Friendslist: Modern Warfare 2 on PC also makes it much easier if you want to party up with your friends, or again, with your clan for a match. You can utilize the friendslist to see when your friends are online, and invite them to your Party. A Party allows you to move from game to game as a group. It’s great for clan matches, because you can party of with your clan and move from public game to public game together. Or if you’re doing a scrim, party up and invite the other clan (who is in a party) and they’ll all join at once. Set up a private match together and play. It makes setting up scrims or games with friends easier and hassle free.Cheat / Hack Free Games: The biggest benefit of using IWnet by far is the fact that you don’t have to worry about joining a server full of aim-bots, wallhacks, or cheaters. Or relying on the server admin of the server to constantly be monitoring, banning, and policing it. Modern Warfare 2 on PC allows us to control the quality of the game much more than ever before as well as utilizing the VAC (Valve-Anti-Cheat) system to keep games clean of hackers and cheaters.All in all, IWNET adds a load of new features that the PC version of our games have never had before and allows us an infrastructure to continue to update and improve on the game post-launch.

DICE comments on the whole issue with
"Battlefield was born on the PC, it grew up with dedicated servers and even when it left the nest and became multiplatform it remembers it's roots. We're doing the PC version of BC2 right. We won't stomach a console port tossed off to some "lesser" studio like our competitors chose to do. We've got our top PC devs working on the PC version side by side with the console team. We don't do ports. It's not the game we'd want to play, and we know it's not the game you want to play either."

I mean, it sounds great and all. But IW is stupid for pulling this. For one, they now have to pay the bandwidth/server bill themselves, which will be a drain if the game falls off in popularity (PC side most likely, as console players are of the gimme gimme type). No PB is great, but all these gaming companies should have invested in an Anti-Cheat software to begin with, instead of relying on half ass'd 3rd parties. I mean, its their stupid game, they know how to combat it. (mostly a problem with paying coders to keep up with the cheaters, which brings me to my first point, they are footing a massive bill for this). Custom content is what helps bring new developers to the market, and this will totally kill that (as far as CoD is concerned).

All in all, what they are really saying is.. "Don't *i-need-a-broader-vocab* with our content, you'll play by our rules."

Anyway i enjoyed the solo gameplay of COD4 but i can tell that i found MW2 annoying (doesnt worth the money) even if they improved some points like animations, etc ... i wont talk about this *i-need-a-broader-vocab* blood flash on the screen when u get hit ...

Apart few funny and original missions, most of the time i felt the game was just bad (scenario quality, interactivity, textures sometimes, mission interest, etc ...), sometimes you know you have some elite army mates in your back but they wont cover you oO.

The multi without dedi nor admin means : no bans, imagine ^^

So IW will host servers ? or what is this going to be p2p servers like warrock or combat arms ?

Not very clear, doesnt seem to be P2P even if it looks like IW will choose where players will connect.
Not being able to create clan servers is the strangest idea ever seen : the multiplayer wont live long.
Maybe the objective like we read somewhere is to get control over players and force them to switch to next COD when they sell it.
